How do side pots work in poker and what is their significance in the game?

In Poker, side pots are created when one or more players go all-in and have different amounts of chips. The main pot is for the player with the highest amount of chips, while the side pot is for the remaining players with lower chip amounts. Side pots allow players with fewer chips to continue betting and potentially win more money, even if they can't win the main pot. They are significant in the game because they add complexity and strategy, as players must consider multiple pots and potential winnings when making decisions.
